I collected a new swarm today from Helen, another low intervention bee keeper who has a Top Bar Hive near the John Radcliffe Hospital. She had kindly caught them in a skep with a sheet under it. Collecting it was simple: tie up the sheet and carry it all away.

The colony from which it comes has been untreated for 2 years. Before that it was intensively managed by a keeper in Wolvercote.

I have placed it in my out-apiary in a new Commercial brood box: Hive F. I'm using frames without foundation, with only the lolly stick guides.

There were quite a few bees crawling near my home hives in a state of moribund helplessness. There was no chance that they could get to the hive entrance and even if they did I doubt whether the guards would have let them back in. Some may have been exhausted, but most either had deformed wings or paralysis. No way back.

Their distress has attracted a few sparrows who feed on them. They perch on nearby fences; they perform a fluttering swoop to grab a bee on the ground; they fly off quickly.

I've been looking at the removable floor of Hive A. There is a steady fall of Varroa mites there. I checked three times and the average is about one mite falling per hour. Some were still alive; a few were clearly immature.

This rate of mite drop puts the colony at severe risk of colony collapse, according to the BeeBase document "Managing Varroa".
